Answer:
The sled slides 0.68m before rest.
Explanation:
Vi= 2 m/s
m= 60kg
μ= 0.3
N= m * g = 60kg * 9.8 m/s²= 588 N
Fr= μ * N
Fr= 176.4 N
a= Fr/m
a= -2.94m/s²
t= Vi/a
t= 0.68 seg
d= Vi*t - a*t²/2
d= 0.68m
An amount of space beteeen 2 things or people
Answer:
finish at the same time
Explanation:
Force equals mass times acceleration. Without friction the net force on both will be equal to component of the force of gravity. Therefore the net force will be mass time acceleration due to gravity times the incline of the hill. Since net force equals mass times acceleration. Now we set net force equals mass times acceleration and the mass will cancel out giving both block the same acceleration and therefore they will finish at the same time
Because my dad had the dominant gene for brown hair, while my mom had the recessive gene, I now have brown hair.
Hope this helped! Good luck! :)

Specific heat of air at constant pressure = 1.005KJ/kg-K Apparently the hot air leaves the house while equal quantity of the cool air passes inside (Neglecting the small specific volume changes between the hot and the cold air) So the situation can be sampled as a scenario where there is continuous draw down of the thermal energy from the air.
